[(OC)4Fe(dppm-P)](dppm = Ph2PCH2PPh2) reacts with [RH2Cl2(CO)4] to give [(OC)4Fe(µ-dppm)RhCl(CO)] with an Fe-Rh bond but no bridging carbonyl group; with [PtBr2(cyclo-octa-1,5-diene)] the product [(OC)3Fe(µ-dppm)(µ-CO)PtBr2] shows some bridging interaction of one of the carbonyl ligands.
                                    [(OC)4Fe(dppm-P)](dppm = Ph2PCH2PPh2)与[RH2Cl2(CO)4]反应生成[(OC)4Fe(µ-dppm)RhCl(CO)],其中含有一个 Fe-Rh 键,但没有桥接羰基;与[PtBr2(
环辛烷-1,5-二烯)]反应生成的[(OC)3Fe(µ-dppm)(µ-CO)PtBr2]显示出其中一个羰基
配体的桥联作用。
